Abstract (en)

[origin: WO2020089578A1] An antenna (300) comprising a housing (310) with an internal cavity (315). The cavity (315) holds an adjustable amount of electrically conductive liquid, and a twin-conductor feedline (350) connects the antenna (300) to a receiving and/or transmitting device. The conductive liquid in the cavity (315) of the antenna housing (310) acts as a first element and receives/transmits signals from/to the first feedline conductor, whilst the second feedline conductor is attached to electrical ground (320).
